Hi
I have several buxus balls around silver birches and recently add some more, one of them is turning yellow.
Can you help pls? Thank you!

The proximity of the ball to the silver birche can cause: lack of moisture, light and nutrients. The light aspect is something you cannot remedy so perhaps regular watering and a feed with any fertiliser with a high nitrogen content may be the way to go.
